What are the ramifications if you don't link purchase orders to the bills. (1) Our business does not really rely on QBO for inventory ie., matching PO's to bills. (2) I was getting an error when I originally tried to "create that link", create a bill from the PO, so I never did that. I assumed that there would be no major ramification for COGS, since that happens on the sales side. I figured to take the time here, to check on this assumption.
